This module combines an 8-digit seven-segment LED display with a 16-button tactile keypad, making it perfect for projects requiring numerical or alphanumeric output as well as user input. The TM1638 chip controls the LEDs, offering easy control through only three wires, significantly reducing the number of required connections.\u003cbr\u003e\u003cbr\u003eThe seven-segment display allows clear and bright visualization of numbers or characters, which can be controlled and updated through a microcontroller. The 16-way keypad provides tactile feedback and is ideal for applications like password input, controlling devices, or selecting options in user interfaces. The module is typically powered by 5V and is compatible with popular microcontrollers like Arduino, offering simple integration with pre-built libraries. This makes it an excellent choice for beginners and professionals alike who are working on projects such as digital clocks, counters, or interactive systems.\n\u003cdiv\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eTechnical Details\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003e3 Wire 8 Bits Seven Segment LED with 16-way Keyboard Module TM1638\u003c\/li\u003e\n\u003cli\u003eTM1638 Digital Tube Driver Chip\u003c\/li\u003e\n\u003cli\u003e8 7-segment LEDs (including decimal points)\u003c\/li\u003e\n\u003cli\u003e16 keys (4x4 matrix)\u003c\/li\u003e\n\u003cli\u003e3-wire interface\u003c\/li\u003e\n\u003cli\u003e8 levels of brightness adjustment\u003c\/li\u003e\n\u003cli\u003e5V DC power supply\u003c\/li\u003e\n\u003cli\u003eLow current consumption\u003c\/li\u003e\n\u003cli\u003eIdeal for digital displays and keypads\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eFeatures\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eTM1638 Digital Tube Driver Chip\u003c\/li\u003e\n\u003cli\u003eOnly requires 3 common I\/O pins for operation, saving MCU resources.\u003c\/li\u003e\n\u003cli\u003eNo need for MCU scanning.\u003c\/li\u003e\n\u003cli\u003e8 8-segment displays (including decimal point)\u003c\/li\u003e\n\u003cli\u003e2x8, a total of 16 keys\u003c\/li\u003e\n\u003cli\u003eSupports 8 levels of brightness adjustment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eApplications\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eDigital clocks and timers\u003c\/li\u003e\n\u003cli\u003eTemperature and humidity displays\u003c\/li\u003e\n\u003cli\u003eEmbedded systems projects\u003c\/li\u003e\n\u003cli\u003eArduino-based displays\u003c\/li\u003e\n\u003cli\u003eCalculator displays\u003c\/li\u003e\n\u003cli\u003eLED-based indicators and controllers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eIntegration with Arduino\u003c\/h3\u003e\n\u003cdiv id=\"p_info\" style=\"text-align: start;\"\u003e\u003cimg alt=\"8 Bits LED Digital tube Module Keyboard Scan and Display Module TM1638 MCU\" style=\"float: none;\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/files\/arduino-and-qyf-TM1638_bb.jpg?v=1646199281\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eSample Code\u003c\/h3\u003e\n\u003cscript src=\"https:\/\/gist.github.com\/labsguru\/2a1ecb73d6d67b7c6988dbf93e8ab623.js\"\u003e\u003c\/script\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003ePhysical Attributes\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eL x W x H (mm): 70 x 70 x 12\u003c\/li\u003e\n\u003cli\u003eWeight (gm) : 30\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003ePackage Includes\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds ls-n\"\u003e\n\u003cli\u003e1 x 3 Wire 8 Bits Seven Segment LED with 16 way Keyboard Module TM1638\u003c\/li\u003e\n\u003cli\u003e5 x Female to female connector\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"KitsGuru","offers":[{"title":"Default Title","offer_id":40708928864437,"sku":"KG599","price":249.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/files\/3_Wire_8_Bits_Seven_Segment_LED_with_16_way_Keyboard_Module_TM1638_10.jpg?v=1739777499","url":"https:\/\/kitsguru.com\/de\/products\/8-bits-led-digital-tube-module-keyboard-scan-and-display-module-tm1638-mcu","provider":"KitsGuru","version":"1.0","type":"link"}
